Should i be hurt or get over it?

In a sense, both. Forgive and forget does not work. You can forgive them for what they said or any wrongdoing that happened between you in the past, but you will never forget. The thing is, you must not hold it against them, even if your lack of relationship is a hard burden to bear. I wouldn't try to confront your family about this issue, because they seem stuck up(for whatever reason). Just live your life and love your child.
